ADUM3402

Quad-Channel, Digital Isolator, Enhanced System-Level ESD Reliability

Manufactured by:

Product Details

The ADuM3400/ADuM3401/ADuM3402 are 4-channel digital isolators based on the Analog Devices, Inc., iCoupler® technology. Combining high speed CMOS and monolithic air core transformer technology, these isolation components provide outstanding performance characteristics superior to alternatives such as optocoupler devices.

iCoupler devices remove the design difficulties commonly associated with optocouplers. Typical optocoupler concerns regarding uncertain current transfer ratios, nonlinear transfer functions, and temperature and lifetime effects are eliminated with the simple iCoupler digital interfaces and stable performance characteristics. The need for external drivers and other discrete components is eliminated with these iCoupler products. Furthermore, iCoupler devices consume one-tenth to one-sixth the power of optocouplers at comparable signal data rates.

The isolators provide four independent isolation channels in a variety of channel configurations and data rates (see the Ordering Guide). All models operate with the supply voltage on either side ranging from 2.7 V to 5.5 V, providing compatibility with lower voltage systems as well as enabling a voltage translation functionality across the isolation barrier. The isolators have a patented refresh feature that ensures dc correctness in the absence of input logic transitions and during powerup/power-down conditions.

In comparison to the ADuM1400/ADuM1401/ADuM1402 isolators, the ADuM3400/ADuM3401/ADuM3402 isolators contain various circuit and layout changes to provide increased capability relative to system-level IEC 61000-4-x testing (ESD/ burst/surge). The precise capability in these tests for either set of isolators is strongly determined by the design and layout of the user’s board or module. For more information, see the AN-793 application note, ESD/Latch-Up Considerations with iCoupler Isolation Products.

Applications

EVAL-3CH4CHEBZ

EVAL-3CH4CHEBZ Circuit Diagram

Product Details

The EVAL-3CH4CHSOICEBZ evaluation board supports triple- and quad-channel standard data isolators in 16-lead SOIC packages. The evaluation board provides a JEDEC standard 16-lead SOIC_N and SOIC_W pad layout and routing appropriate for the evaluation of supported devices. The evaluation board provides a connection to power supplies by screw terminals and includes optimal bypass capacitors. Signal channel routing supports signal distribution, loopback, and provides positions for loads referenced to the VDD1/VDD2 and GND1/GND2 planes. Signal sources can be conducted to the board through header pins or edge-mounted SMA connectors; SMA connectors must be ordered separately.

Positions for through-hole 0.2 inch headers compatible with active probes are provided on the printed circuit board (PCB); probe header pins must be ordered separately. The board follows PCB design practices for 4-layer boards, including a full power and ground plane on each side of the isolation barrier. No other EMI or noise mitigation design features are included on the board. In cases of very high speed operation or when ultralow emissions are required, refer to the AN-1109 application note for additional board layout techniques.

Full specifications for the device under test (DUT) are available in the corresponding product data sheet, which should be consulted in conjunction with this user guide when using the evaluation board.

EVAL-EZLINX

Product Details

The ezLINX™ iCoupler® Isolated Interface Development Environment provides developers with a cost-effective, plug and play method for evaluation eight physical layer, digitally-isolated communication standards (USB, RS-422, RS-485, RS-232, CAN, SPI, I2C, and LVDS). The Blackfin® ADSP-BF548 processor is used to run the uCLinux operating system and allows for easy customization through the open source hardware and software platform. Development time is significantly reduced for embedded designers and system architects who are designing and evaluating isolated communication standards. The interfaces on ezLINX use ADI's isolated transceivers with integrated iCoupler® and isoPower® digital isolator technology.
